I'm using the following command:
ffmpeg -i file.mp3 -c:a copy -map 0:2 -f alsa -shortest file.avi
I am getting output as a text file with the audio contents instead of a video. Can any one explain what I am doing wrong here?
A:
You need to use the alsa.aac container.
ffmpeg -i file.mp3 -f alsa -i pulse -c:a copy -map 0:2 -f alsa -shortest -i audio.aac file.avi
Unbeknownst to much of the world, 90 percent of the Earth is covered in water. This means that the problem of water storage and accessibility isn’t a problem in the developing world, but a problem in North America and Europe, where homes are typically located far from rivers or lakes, or even indoors. In the United States, the nation’s population is booming, and water demand is increasing as cities and homes are being built, but water management and protection isn’t keeping up. According to the United States Geological Survey, the demand for water in the U.S. increased by roughly two million acre-feet per year, or more than 300,000 acre-feet, between 2005 and 2010. The number of acre-feet is the measurement for the total amount of water in a typical lake or reservoir.
On top of population growth, drought, and increasing demands from consumers, the United States faces a serious problem with water infrastructure and storage. A lack of large water storage facilities and the lack of research into infrastructure mean that much of the American population lacks basic access to water. More than 40 million Americans live in homes without access to tap water, while 20 million Americans lack access to sewer services. Additionally, many public parks and public property are facing extreme water shortages. One such area of concern is New York City, which saw $112.7 million worth of water filtration systems installed to protect homes and businesses.
Although water systems are an essential part of human existence, they can be very expensive, as the case of Los Angeles is showing. The city is facing the issue of a lack of water storage and a very high rate of water consumption. The city faces the responsibility of collecting, treating, and transporting water to the homes and businesses in the Los Angeles Basin, but it is facing numerous issues in order to accomplish this, with one 01e38acffe

Hi! I know this is kind of off-topic but I was wondering which blog platform are you using for this site? I’m getting tired of Wordpress because I’ve had problems with hackers and I’m looking at options for another platform. I would be great if you could point me in the direction of a good platform.
Today, I went to the beach front with my kids. I found a sea shell and gave it to my 4 year old daughter and said “You can hear the ocean if you put this to your ear.” She placed the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
